If any of you have, or are considering purchase of the RayMarine DSM 250 sounder (ie. in RayMarine's HSB2 system...), check out the article in the May 2003 issue of "Yachting" magazine (p40). I would scan it; but don't have a scanner handy.

Overall, the article is very positive on the DSM250. The short short article describes RayMarine's "new" approach to digital signal processing of the sounder data stream. Some of the info was way beyond my non-geek comprehension. An example:

"In high-performance radio DSP receivers, the incoming signal is converted into a digital bit stream that is worked upon with a complex signal extraction algorithm stored in the radio's digital memory. The improvement boaters hear is remarkable.
Just as remarkable is the improvement in fishfinding with Raymarine's DSM 250. It converts sonar signal echoes from analog (varying signal strength) to a high-speed (56Mhz) flow of 36-bit digital words. The DSM 250's control algorithm then continuously adjusts the system's operating and signal-processing variables....yada, yada, yada."

I didn't understand more than half of what I just typed.

...but a couple of screen shots demonstrated that the color screen is very pretty!
